Wednesday marks 2023's perihelion day, when Earth will be about 3 million miles closer to the sun than at its farthest point in orbit. SWIRLING ERUPTION FROM THE SUN SHOWCASES NOAA SATELLITE'S ABILITY TO FORECAST SPACE WEATHER Perihelion doesn't always happen on the same day or time every ...
The sun is located at one of the focuses of the earth’s elliptical orbit, and therefore the distance between the earth and the sun changes during the course of a year from 147,117 million km (at the perihelion) to 152,083 million km (at the aphelion). The semimajor axis of the ...
Aphelion, in astronomy, the point in the orbit of a planet, comet, or other body most distant from the Sun. When Earth is at its aphelion in early July, it isabout 4,800,000 km (3,000,000 miles) farther from the Sunthan when at its perihelion in early January. When was day time...
Due to their tidal interaction, the Moon recedes from Earth at the rate of approximately 38 mm/yr. Over millions of years, these tiny modifications—and the lengthening of Earth's day by about 23 µs/yr—add up to significant changes. During the Devonian period, for example, (approximate...

Perihelion (closest approach to the sun): 91,402,640 miles (147,098,291 km) Aphelion (farthest distance from the sun): 94,509,460 miles (152,098,233 km) Length of solar day (single rotation on its axis): 23.934 hours Length of year (single revolution around the sun): 365.26 days ...
Perihelion 2025 occurs onJanuary 4, 2025 at 8:28 a.m.At that point in its orbit, the Earth is over 91 million from the Sun, a difference of about three million miles from its farthest point, aphelion. (The actual number varies year over year.) ...
the times when the Earth lies at its closest and farthest points from the sun roughly coincide with two significant holidays. We're closest to the sun around New Year's Day and farthest from the sun around Independence Day. Actually, depending on the year, the date of perihelion can vary ...
On average, the Earth orbits 93 million miles (149,600,000 km) from the Sun. This distance is defined as one Astronomical Unit (AU). The Earth is closest to the Sun (this is called perihelion) around January 2 each year (91.4 million miles = 147.1 million km); it is farthest away ...
Do Aphelion and Perihelion Cause the Seasons? It’s not the distance from the Sun that causes our seasons. Seasons happen because the Earth’s axis is tilted at an angle. It’s because Earth orbits the Sun on a tilt that our planet gets more or less of the Sun’s direct rays at dif...
